We also have a stage box expansion unit. So we are running 50 in puts but not all are visible when I select input on the desk top. The question is why do I not see all the inputs or how can I add the ones I don't see?
If the stage box is not immediately recognized, you have to reset the configuration on the console to make it appear as a selectable I
input. Have you scrolled past all of the inputs to see if the MADI inputs are available? What option card do you have installed?
